GLASS-CUTTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 368,928, dated August30, 1887.

Application filed October 9,1886. Serial No. 215,768. (No model.)

To all whom it may concern.-

Be it known that l, FRED BUCK, a citizen of the United States,residingat Cleveland, county of Cuyahoga, and State of Ohio, have inventedcertain new and useful Improvements in .Glass- Outting Apparatus; and Ido hereby declare the following to be a description of the same and ofthe manner of constructing and using the invention in such full, clear,concise, and exact terms as to enable any person skilled in the art towhich it appertains to construct and use the same, reference being hadto the accompanying drawings, forming a part of the speeication, theprinciple of the invention being herein explained and the best mode inwhich I have contemplated applying that principle so as to distinguishit from otherinventions.

Figure l is a perspective view of the glasscutting board with glass andruler on same. Fig. 2 is a reverse perspective View of the ruler. Fig. 3is a face perspective view of the ruler. Fig. 4 is a vertical sectionalview taken longitudinally through the ruler and transversely through theboard, as said parts are shown in joint operation. Fig. 5 is a detailedperspective view of gage F.

The cutting-board A is provided along its longitudinal upper edgeportion with a series of upright pins, a, said pins connected togetherby a top rail, B. The lower longitudinal edge of the board is providedwith a series of horizontal pins, b, connected together at theirprojecting extremities by a rail, O.' The respective pins of the upperseries have their longitudinal axes in the same respective planes withthe respective pins of the lower series, said respective planes c beingtaken vertically and extending from top to bottom of the board. Thesedifferent vertical planes are taken an inchapart from one another in aseries extending throughout the width of the board. Intersecting saidplanes o are the cross-planes d, also taken vertically relative to theboard, the series of them extending from the top to the bottom of theboard. Said planes d are also taken an inch apart from each other. Thetop face of rail B, the

upper edge of rail C, and the lower longitudinal edge portion of theboard. all are respectively provided with a series of numeralscorresponding to each other as they mark where therespective planes opass through. The two side edge portions of the board are respectivelyprovided with a series of numerals corresponding to each other, as theymark the respective cross planes d.

The cutting-ruler D is provided at its upper edge with atransversely-recessed lip, e, On the face of the ruler adjacent to saidlip are drawn a series of longitudinal gage-marks, f, corresponding tothe different fractional portions of an inch. A gage, E, has adjustablebearing on said lip e, and is of thickness so that its upper surface isflush with the upper surface of the ruler. It is provided with atransverse slot, g, in which is iitted an upright stud, h, rigid withlip e. A thumbpiece, l, is threaded on said stud, so that its lower endvmay have bearing on the adjus'table gage, clamping the latter at anydesired point of lateral adjustment on the lip. Said gage has itsright-hand side formed parallel with the rulers length, while itsleft-hand side is formed at an angle of about forty-five degrees to therulers length. The lower end portion of the ruler has its under surfacepro- Vvided with a transverse recess, m, in which.

gage F fits. Said gage is provided with longitudinal slot n, in which isfitted screw o, passing through a suitable hole in the ruler.. The headof the screw has bearing against the index-face of the gage F, so as toclamp the latter at any desired point of adjustment in said recess m bythe tightening of thumbpiece p, threaded on the ripper projectingportion of said screw. Said lgage F is provided at its right-hand sidewith a depending prong, r. This prong 1" ts into the respective openingsformed between any two consecutive pins b, while prong j, formed as theuppereXtremity of gage E, ts into the respective openings formed betweenany two consecutive pins a, said two gage-prongs being of such size aswhen iitted into said respective openings to be snug therein and to holdthe ruler rm in position on the board.

The under face ofthe ruler is provided with a series of longitudinalgage-marks, s, the duplicate of gage-marks f. This provision oflaterally-adjustable gages on the ruler is of use in the cutting ofglass at any size other than a IOO whole inch size. For instance, ifglass is to be cut of any size which necessitates a fraction of an inchin the ruling of it, these two gages on the ruler maybe respectively setin from the right-hand edge of the ruler a distance equal to saidfraction of an inch, whereupon the ruler may be nsed with said two gageshaving their projecting prongsj r tted into openings between therespective series of pins they engage the same as though the glass to becut were of a whole inch size.

It will be apparent that when the two gages areset with their right-handsidein line with the right-hand side of the ruler said ruler .may beused to accurately cut glass of a whole inch size; but when glass is tobe cut of any size involving a fraction of an inch, said gages are to berespectively set with their right-hand sides in a longitudinal lineparallel with the right-hand side ofthe ruler, but at a distance to theleft of the same equal to the fraction of the inch at which the glass isto be cut.

It will be apparent that other mechanical means may be employed insubstitution for the specic means herein shown to secure a lateraladjustment of the sliding gages, and hence my invention contemplates,broadly, thefprinciples of invention set forth in the claims.

1. A glass-cutting board provided at one of its longitudinal edgeportions with a series of upright pins and provided at itsoppostelongitudinal edge with a series of horizontal pins located in aplane below that of the first series of pins, substantially as setforth.

2. The combination, with a glass cutting board provided at onc of itslongitndinaledge portions witha series of upright pins and provided atits opposite longitudinal edge with a seriesofhorizontal pins located ina plane below that of the iirst series of pins, oi' a rule adapted atits upper end to t in between the openings formed between consecutivepairs of said upright pins, and provided at its lower end with adepending prong tting between the open ings formed between consecutivepairs of said horizontal pins, substantially as set forth.

3. The combination, with a glass cutting board having its upperlongitudinal edge provided with a series of upright pins and its lowerlongitudinal edge provided with a series of horizontal pins, of a ruleprovided at its upper end with a transversely-adjustable horizontal gageand at its Lower end with a depending transversely adjustable gage, saidtwo gages respectively fitting between the openings formed betweenconsecutive pairs of said upright and horizontal pins, substantially asset forth.

4. The combination, with a glass cutting board having its upperlongitudinal edge provided with a series of upright pins and its lowerlongitudinal edge provided with a Series of horizontal pins, ofa ruleprovided at its up'- per end with an angularly-formed transverselyadjustable gage and at its lower end with a depending transversely-adjustable gage, said two gages fitting, respectively, between the openingsformed between consecutive pairs of said two sets of pins, substantiallyas set forth.

5. The combination, with a ruler, of two gages, E F, one located at itstop end and the other located at its lower body portion, said gagesrespectively adjustable in planes transverse to the ruler, and clampingmechanism which secures said gages in set adjustment, substantially asset forth.

6. Thecombinatiomwitharuler, D, provided at its upper end with arecessed lip, c, of a gage, E, fitting on the latter, and a clampingdevice which secures said gage in set adjustment on said lip,substantially as set forth.

In testimony that I claim the foregoing to be my invention I havehereunto set my hand this 6th day of October, A. D. 1886.

FRED BUCK.
